All lights mod with selectable fogs

[David Whitcomb]

So as normal I'm a bit late to the party. I'm doing an upfit of a 2022 Silverado 3500HD into a fire truck and needed some specific pinouts for the BCM. With help of this thread I was able to quickly find the 10 pages in the upfitter reference document pertinent to the BCM and it's connections.

 

If it helps anyone else, you can get the full 1k page upfitter document freely from gmupfitter.com

When looking through the document, I was able to identify pages 379-388 were all the details of the BCM pinouts. 

 

For a savvy DIY'er, this will have EVERYTHING you could possibly need.

Has anyone figured out how to get the task lights to come on with the puddle lights?

Do you have a BCM pinout for a 2016 GMC Yukon Denali you would be willing to post?
